Hi,
Is the Mathmod-1.0-alpha version working ?
If yes then just copy the "plugin" folder (from bin )
In your mathmod-1.0-beta installation folder ("program files/mathmod" by default)_________________Cheers,

Hi Denisc,
What do you mean by the examples don't work?
can you view the list of 142 examples in the tree list?
If yes, then every thing should be ok.
To add a new model to "My selection" section:

To visualize a new model:
* If you made some changes in the "F(x,y,z, t)=0" tab, then you should use the "(update|Add|cut) & Run" buttoo (see the image on top)
* If you made some changes to the script by using the "script editor" section, then click the "Run" button (see the image bellow)

Hi Denisc,
It looks like you have some problem with the install program.
I'll suggest to

1) Delete all MathMod folders in the "C:\Program Files (x86)\MathMod"
2) redownload the last 64Bit MathMod-1.0-BETA(WIN64Bit) from: https://sourceforge.net/projects/mathmod/files/MathMod-1.0/Beta/
You should redownload the last 64Bit version because I changed it three times. I have also win7 and it works fine on my machine_________________Cheers,
